Wheel Impact Load Detector

70% of Wheel Impact Load Detector (WILD) Systems in India - Installed & Maintained by ApnaTech

The Wheel Impact Load Detector, or WILD, is an intelligent, unmanned wayside system that measures the impact load of wheels on the railway track. ApnaTech installed the first WILD system in India, over a decade ago. Since then, our solution has proven to be superior to imported systems in terms of accurate fault detection in all benchmarking studies. Our solution is proudly Made in India and for India.

The apnaWILD system measures and monitors:

  • Impact loads caused by wheel defects according to the defined threshold and the severity of defect
  • Number of axles and axle condition
  • Speed of each axle
  • Average speed of the train
  • Average dynamic wheel load for all wheels
